Claims (3)

  1. Compresseur à spirale comprenant :
    un premier composant coulissant (7) formé en forme annulaire et présentant une surface coulissante (7a),
    un second composant coulissant (8) ayant une surface coulissante (8a) ; et un dispositif d'entraînement excentrique configuré pour faire coulisser la surface coulissante (7a) du premier composant coulissant (7) avec la surface coulissante (8a) du second composant coulissant (8) de sorte qu'un centre du premier composant coulissant (7) dessine imaginairement un cercle qui est excentrique par rapport à un centre du second composant coulissant (8) tout en maintenant un état de non-rotation du premier composant coulissant (7) par rapport au centre du premier composant coulissant (8) en vue en plan,
    dans lequel une pluralité de rainures (70) ne communiquant ni avec un espace sur un côté de diamètre intérieur du composant coulissant (7, 8) ni avec un espace sur un côté de diamètre extérieur du composant coulissant (7, 8) sont formées dans la surface coulissante (7a, 8a) d'au moins l'un du premier composant coulissant (7) et du second composant coulissant (8) de manière à être agencées dans une direction circonférentielle du composant coulissant (7, 8),
    l'un parmi l'espace sur le côté de diamètre extérieur et l'espace sur le côté de diamètre intérieur est un côté haute pression, le reste de l'espace sur le côté de diamètre extérieur et de l'espace sur le côté de diamètre intérieur est un côté basse pression,
    caractérisé en ce qu'une surface inférieure (70b) de chaque rainure (70) est une surface inférieure plane s'étendant parallèlement à la surface coulissante (7a, 8a) d'au moins l'un parmi le premier composant coulissant (7) et le second composant coulissant (8), une surface inclinée ou une surface courbe,
    chaque rainure (70) présente une dimension radiale (L1) dans une direction radiale de la surface coulissante (7a, 8a) d'au moins l'un parmi le premier composant coulissant (7) et le second composant coulissant (8), ladite dimension radiale (L1) formée entre un centre (P) et une surface de paroi (70a) de chaque rainure, le centre (P) étant un centre géométrique sur un cercle virtuel (VC) comme milieu radial de la surface coulissante, et la surface de paroi (70a) de chaque rainure (70) s'étendant dans la direction axiale, la surface de paroi étant orthogonale à la surface coulissante plane, ladite dimension radiale (L1) de chaque rainure étant plus longue qu'une dimension radiale (L2) d'une partie cordon entre la surface de paroi (70a) et une périphérie côté haute pression de la surface coulissante (7a, 8a) de l'un parmi le premier composant coulissant (7) et le second composant coulissant (8), et
    la dimension radiale (L3) de la partie cordon entre une périphérie côté basse pression de la surface coulissante (7a) et la surface de paroi (70a) est égale à ladite dimension radiale (L2) d'une partie cordon entre la surface de paroi (70a) et une périphérie côté haute pression de la surface coulissante.
  2. Compresseur à spirale selon la revendication 1, dans lequel chacune des rainures (70) est de forme circulaire.
  3. Compresseur à spirale selon la revendication 1 ou 2, dans lequel l'un parmi le premier composant coulissant (7) et le second composant coulissant (8) présente une largeur radiale inférieure à une largeur radiale du restant de l'un parmi le premier composant coulissant (7) et le second composant coulissant (8).
